EUGENE BEGGS, OF PATERSON, NEV JERSEY.

BOILER.

SPECIFICATION forming part of Letters Patent No. 415,894, dated November26, 1889.

Application filed February 13, 1889. Serial No. 299,778. (No model.)

To all whom it may concern:

Be it known that I, EUGENE BEGGS, a citizen of the United States,residing at Paterson, Passaic county, State of New Jersey, have inventeda new and useful Improvement in Boilers, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof.

My invention relates to water-tube boilers, and has for its object aWater-tube boiler wherein is secured cheapness of construction, economyof fuel, and a boiler which is easily taken apart for repairs, cleaning,removal, the.

The obj ects sought I attain by the construction shown in theaccompanying drawings, which will be hereinafter fully described andclaimed, in which- Figure l is a side elevation of the boiler, thereservoir being removed in such figure. Fig. 2 is a transverse sectionalelevation on line w to of Fig. l. Fig. 3 is a longitudinal sectionalelevation of the same on line so of Fig. 1l. Fig. 4 is a front elevationof the boiler. Fig. 5 is a rear elevation of the same. Fig. 6 is a planon line y y of Fig. 3. Fig. 7 is adetail of headers, water-box tubes,die., part sectional, on line .e z of Fig. 6j Fig. S shows in elevationthe position of the tubes in the water-box, and Fig. 9 is a sectionshowing how the water-chainbers, the., are connected.

A represents a water-tube boiler of new construction, in the fire-box Bof which is arranged a series of grates B. The grates B the edges ofwhich are rounded off, are adapted to act in concert with rotary barsB2, which latter are arranged with reference to the grates between andon each side of the same, which, while turning upon their axis when thegrates are being` operated, accommodate themselves to the movement ofthe grates, which action of the bars tends to crush obstructingparticles and prevent clogging. The grates B, which are arranged in lcommon with rotary bars B2 in the ash-box ever, does not form a part ofthe present invention, and many other approved forms of grate may beused in place of the one described.

On each side of the lire-box B above the grates B where combustion takesplace, is arranged waterchambers D, that connect withtransversely-arranged wateihchambers Dzby means of aconnecting-joint D.These water chambers D and D5a are arranged around the nre-box withreference to each other,and, being connected, form a waterspace on allsides of the re-box for the circulating of water to be heated, ashereinafter stated. The chambers D are provided with lugs D3, whichlatter pass through the chambers and project into the iire-box, thisconstruction of the chambers D,While it furnishes increasedheating-surface for the chambers, also gives additional strength to thesame.

At the ends of the frame there are arranged headers F F which headershave formed in the outer ends of the saine, outside of the boiler-frame,recesses E to accommodate bolts E, by which the boiler-frame is fastenedtogether, and by'which the frame is firmly held in position, the boltsnot being subjected to heat to cause expansion and contraction of thesame. In addition to the recessed ends E to accommodate bolt E, by whichthe boilerframe is held in position, theheaders F F are provided withwater-spaces F3 and a connection F4, by which the headers are adapted toconnect with water-boxes G, that are arranged in the fire-box B withreference to the headers and their connection therewith by means of aconnection F4, as shown. The Waterboxes G, which are provided with lugsF2, that jam against the headers to hold the boxes G in position, arealso provided with two sets of tubes H, which tubes are arranged in thewater-boxes, as shown in Figs. 2 and 8 of the drawings, there beingconsiderable space left between each one of the upper set of tubes inorder that the lower set of the same may be conveniently cleaned,repaired, removed, &c.

The headers F F connect with a reservoir L by means of pipes K K', andalso connect with chambers D by means of pipes N N', as shown. The waterpasses from the reservoir L through the pipe K into header F, and fromthence the water passes through the pipe N into chambers D and D2 andthrough IOO the tubes H into box G'. The Water having been heated Whilepassing through the chambers and tubes around and over the iire-box,asstated, the heated Water and steam pass from the chambers D throughpipe II' and from box G' into header F', and from header F' through thepipe K' into the reservoir L, to be returned through the reservoir,pipes,

headers, tubes, and chambers, dac., as indicated by arrows, to bereheated. A continuous circulation of Water to be heated and reheated isthus maintained without loss of heat from the nre-box, with aproportionate saving of fuel.

The connections D' and F' between the lchambers D D2, headers F, andboxes G, which are composed of the usual brass bush, as shown in Figs. 7and 8, may be formed with a union or other connecting means Withoutchanging the nature of` my invention; hence I do not confine myself tothe precise construction of the connections shown.

The boiler-frame is composed of a cast-metal fire-box B, that rests onlugs A2, formed theres for in the ash-boXA', While the remaining portionof the boiler-frame is formed of a Wrought-iron plate or plates o, whichlatter are fastened to the fire-box B by set-screws P, the en'tir'estructure being held in position by bolts E and n and set-screws I), asshown, and may be taken apart for repairs, cleaning, removal, &c., in afeW minutes. The top of the frame is provided with asbcstus covering R,which is arranged in angle-irons S, supported by standards J', While abottom plate R' is arranged in and supported by like angle-irons S',Fig. 3; There is also supported by standardsJ' a smoke-box J, which boxis provided With a door J2, which latter affords an easy Way oflcontrolling` the draft.

Having described my invention, I claim as new and desire to secure byLet-ters Patentl. In a boiler, the combination, with the firebox, of thelongitudinal Water-heating chambers D in the outer Wall of the fire-box,provided With a series of strengthening-lugs D2, extending across theinside of said chambers and projecting into the {ire-box, the transverseWater-heating chambers D2 in the end Walls of the lire-box, and theWater-tight connecting-joints D' bet-Ween the said chambers andpermitting the Water to circulate all around the fire-box, substantiallyas set forth.

2. In a boiler, the combination, with the headers F and F', providedwith connections F4, for communicating With the Water-boxes, of thebolts E at each end of the headers for holding them in position, theWater-boxes G, secured to said connections, and the tubes Il, unitingthe Water-boxes, substantially as and for thepurpose set forth.

3; The water-boxes G, having lugs F2 and two sets of tubes H', the boxesarranged With reference to headers F F' in the fire-box and connectedwith said headers, by which Water is circulated through the headers,boxes, and tubes to be heated, substantially as described.

4. The boiler-framecompos'ed of a castmetal fire-box A and-B andv plateor plates 0, the frame held in position by bolts E n and set-screws P,substantially as described and shown. y

5. The combination, with the headers F F' and chambers D, of thereservoir L, pipes K K', and pipes N N', all arranged to operatesubstantially as described and shown.

G. The combination, Withthe boiler-frame,

of the covering R, plate R',box J, door J2, and

supports J', as described and shown.
